Additive Manufacturing of Novel Nickel-Based Alloys for High Performance Heat Exchangers

The development of advanced materials combined with additive manufacturing offers unique advantages when fabricating complex components such as heat exchangers. The advancement of nickel-based superalloys designed for additive manufacturing with improved long-term stability at temperature enhances performance and enables highly efficient extreme environment heat exchangers for power generation and high-speed aircraft. ATI has developed new superalloys that improve high-temperature performance, creep properties, and long-term stability compared to commonly used alloys that are additively manufacturable, enabling extended service life of components in extreme environments. This presentation will discuss powder production, additive manufacturing development process, and resulting mechanical, thermophysical, and environmental properties of these alloys.
